Use a transom pickup and drill and tap a fitting into the box below the impeller

I don't think a transom mounted pickup will be legal for that - would need a nosecone if you need more water pressure!

Follow the link at the top of the page to Bobs Machine Shop. Good quality Nose Cones perhaps a little large but they fit a 90 yam ok.
